[3] Glassman has also worked as a journalist, magazine publisher, and business writer, and in the field of economic policy development.

In 2003, the Washington Monthly credited Glassman with inventing "journo-lobbying" by writing a large number of seemingly independent opinion columns that aligned closely with the interests of his lobbying clients; his output included columns that questioned the science behind climate change.

[7] From February 2010 to June 2012, he hosted "Ideas in Action", a weekly PBS series on public policy issues.

[9] In 2003 Glassman served on the U.S. government's Advisory Board on Public Diplomacy in the Arab and Muslim World.

[2] He served in the position from June 2008 to January 2009, leading the governmentwide international strategic communications effort.

[8] In an interview in 2009, he put forward a case that in the long run the Iraq War will prove to have been a positive decision, saying that it will be ultimately "beneficial to the war of ideas in the sense that a functioning democracy that we hope will be stable and prosperous now exists in the Middle East, and is showing other nations and other people what a democracy looks like."

[14] Nobel laureate Paul Krugman argued on his faculty website that the book contained basic arithmetic errors and was "very silly".

[16] John C. Bogle, then senior chairman of The Vanguard Group, however, said in a blurb for the book "While there will be bumps--maybe big ones--along the way and the road may be surprisingly long, Dow 36,000 offers superb advice.

[17] David Malpass, who later served as president of the World Bank, said, "Glassman and Hassett's ideas are timely and thought-provoking.

Either we are in a bubble with inefficient financial markets, or else past theories on stock prices and price-earnings multiples have to be revised.

"[14] In Safety Net, he argued that "the world has changed" over the past decade; that the U.S. relative economic position had declined and that the risk of catastrophic events had increased.

[18] In 2012, he wrote the introduction of The 4% Solution: Unleashing the Economic Growth America Needs, published by the George W. Bush Presidential Center.

In March 2013, he reverted to his former position, stating in an article for Bloomberg L.P. that while he had underestimated the level of volatility in world events, he believed that reaching 'Dow 36,000' was still possible within less than a decade with the right policies.

[20] His second book, The Secret Code of the Superior Investor: How to Be a Long-Term Winner in a Short-Term World, was published by Three Rivers Press in December 2002.

It offered advice for finding the best individual stocks and mutual funds even in uncertain times and volatile markets.
